SummaryAsteroid 1998 KY26 is a decametre-sized, rapidly rotating body that has been selected as a target for the extended Hayabusa2# mission. Understanding its physical properties is crucial for optimizing mission planning, as it presents both challenges and opportunities for asteroid exploration. This study[1] provides a detailed characterization

Understanding the physical characteristics of small Solar System bodies is important not only for refining formation and evolution models but also for space mission operations. Although several kilometre-sized asteroids have been visited by spacecraft, asteroid 1998 KY 26—the final target of Hayabusa2#, the extended mission of the Japan Aerospace

On 2022 September 26, NASA's DART mission intentionally impacted Dimorphos, the moon of near-Earth asteroid (65803) Didymos, changing the binary system's orbital period. The system was studied intensively from the ground over the ensuing months until February 2023 when its brightness and low solar elongation precluded further observations. These

Ultrafaint dwarf galaxies (UFDs) are ideal for studying dark matter (DM) due to minimal baryonic effects. UFD observations suggest cored DM profiles. We find that the core radius–stellar mass scaling predicted by fuzzy dark matter (FDM) is at 6 . 1 σ tension with UFD observations. Combining observations from 27 UFDs, the required FDM mass m a = 3

Interaction phenomena between atmospheric layers in planetary atmospheres give rise to highly complex exchanges influencing thermal structure, composition and dynamics. In particular, the question of hydrodynamic escape in exoplanet atmospheres is a key issue for quantifying the mass loss in these atmospheres. Short-period exoplanets subject to

We present the first results from ATLAS-Teide, the new unit of the Asteroid Terrestrial-impact Last Alert System (ATLAS) installed by the Instituto de Astrofísica de Canarias (IAC) at the Teide Observatory (Tenerife, Spain) in January 2025. ATLAS-Teide is part of the IAC's "Strategic Plan of the Canarian Observatories," supported by projects
